In plain words
Concluding the import conveyed through the narrative, the teaching declares: This wisdom of the Self, sought out by Bhrigu and imparted by Varuna, rests securely in the supreme space within the heart's cave, in the absolute, non-dual bliss, unfolding outward from the physical food-sheath. Whoever follows this exact path of disciplined inquiry and directly realizes that infinite bliss as Brahman becomes anchored immovably in that supreme reality, truly becoming Brahman itself. The empirical fruit of this realization is then set forth: 'He possesses food, and abundant food is his,' making him a true consumer of the universe. Mere biological existence does not confer this distinction, for everyone eats; rather, through knowledge, he becomes like a blazing fire. He attains true greatness—greatness in descendants, in cattle and wealth, in the spiritual radiance of self-mastery, and in enduring renown won through noble character.
Close to the Sanskrit
Having concluded the meaning accomplished by the narrative through its own statement, [the text] declares: This very Varuni knowledge, known by Bhrigu and declared by Varuna, is established in the supreme ether, in the cave of the heart, in the supreme non-dual bliss, and originates from the physical self. Whosoever else, by austerity alone as the means and by this very sequential path, having deeply entered, knows Brahman as bliss, he indeed, through the establishment in knowledge, becomes firmly established in the supreme bliss and Brahman, he becomes Brahman itself—so it is said. And the visible fruit of that is declared: 'Possessing food, abundant food belongs to him'—thus he is an eater of food. Simply by existence every ordinary person possesses food, but if so, there would be no special distinction arising from knowledge. Similarly, 'eating food,' he is an consumer of food, meaning he becomes a blazing fire. He becomes great. By what is this greatness? Through progeny such as sons, through cattle such as cows and horses, and through spiritual luster arising from calm, control, and knowledge. He becomes great through fame, reputation, and righteous conduct.
